Further, LTM probes are also an effective and trouble free tool for maintaining consistent pump sump levels particularly when there is froth in the box, as well as maintaining general tank water levels.

LTM PROBE BENEFITS AND FEATURES

Conductive vs. capacitive

1% accuracy, 1% linearity

Near instantaneous readings

Extremely stable operation

Very low maintenance

Easy to understand and use

HARMONICS

A 1 hour strip chart example provided below from an actual operation demonstrates typical LTM measurement stability vs. a typical ultrasonic-float ball target measuring assembly. The LTM probe was installed as a ‘follower’ (red trend line) and not tied into the pulp level control scheme, just provided level monitoring for comparison. The ultrasonic trend line is in green.

Also, note the harmonics on the Pulp and Water Level Monitoring LTM Probe is much lower which means less system ‘noise’. Despite the ultrasonic signal being damped by signal updates every three seconds, there was vastly greater system signal noise vs. the level probe that updated 10x per second.
